The Controlled-Environment Lighting Laboratory (CELL) is a vertical farming research facility at Michigan State University focused on the indoor production of high-value specialty crops. Dr. Erik Runkle in Horticulture developed CELL for:
CELL consists of two independently controlled and refrigerated growth rooms, each with 12 deep-flow hydroponic shelves. Sole-source lighting in CELL utilizes customized, state-of-the-art light-emitting diodes (LEDs) developed in collaboration with OSRAM and OSRAM Opto Semiconductors. Customized software enables digital light control of individual shelves, allowing for temporal alternations of light quality and intensity. Ph.D. candidate Qingwu (William) Meng is leading research on lighting to produce leafy greens with desired attributes through light-mediated regulation of extension growth and leaf size, leaf thickness (texture) and color, as well as taste and nutritional value. Here's a glimpse of our first test crop in CELL (spring, 2017), followed by a video showing more recent research (winter, 2017) on the indoor production of leafy greens. Videos by Qingwu Meng.
We recently initiated a new research project entitled "Development of Sole-Source Lighting Guidelines for the Production of Floriculture Transplants", partly supported by the Mengzi Zhang and Ph.D. candidate Yujin Park, will provide a better understanding of how sole-source lighting (primarily from blue, red, and far-red LEDs) affects growth and development on a range of floriculture crops, especially annual bedding plants.. This project, led by M.S. candidate
CELL is located on the first floor of the Plant and Soil Sciences Building (room A154). Students and visitors can look inside CELL through its large windows from the corridor, which can potentially spark their curiosity about the emerging vertical farming industry. We're also pleased to participate in the MSU Science Festival on April 14, 2018. Learn more about our Growing Food Without Sunlight or Soil tours held during this campus-wide event.
